Prijevod "grenades" u hrvatski

U.S. government studies have found that the grenades have a failure rate of 14 percent or more, meaning that for every 155-millimeter cluster shell that is given to Ukraine and fired, 10 of the 72 grenades it disperses are likely to fall to the ground as hazardous duds.

Studije američke vlade otkrile su da "zvončići" imaju stopu zatajenja od 14 posto ili više, što znači da će za svaku 155-milimetarsku kazetnu bombu koja se daje Ukrajini i ispaljuje, 10 od 72 "zvončića" koji se rasprše vjerojatno pasti na tlo kao opasne neeksplodirane naprave.
